We see a Mercenary Holy Warrior clad in dark studded leather armor astride a warhorse.  Storyline wise he has had a near death experience, had his body possessed while his spirit was in a coma and traveled the outer planes, so his exterior might be a little worse for wear.  But he is the consummate lawful good devotee, so his expression should capture a level of resolve or unshaken faith - maybe with a small / slight corona / nimbus of light.  This is also a character of substantial charisma that not only commands an army of mercenaries, but does so enforcing a strict code of lawful behavior.
